Project Overview • Proximity Sensing • Zigbee RSSI • “Manual” mapping of –dBm to feet • Audio transmission • Zigbee wireless transmission • Sampling and reconstruction • Peripheral tamper detection • Reports wristband disconnect or severing
Design Challenges Faced • Size constraints • Battery Life • PCB tracing errors • Datasheet errors and/or misunderstanding • Audio transmission
ECE 270/362 Knowledge Used • Microcontroller structure (ECE362) • Baud rates (ECE362) • Pulse-Width Modulation (ECE362) • Analog-to-Digital conversion (ECE362) • Clock cycles (ECE270) • Voltage HIGHs and LOWs (ECE270) • Pin transition times (ECE270)
